Product Description
The Yokogawa EJA430A Pressure Transmitter has long been a cornerstone in industrial pressure measurement, trusted for its reliability and precision. As technology advances, Yokogawa has introduced enhancements to the EJA430A series, bringing new features and improvements while maintaining the core strengths of the original design. This overview delves into the specifications, applications, and key differences between the original and new Yokogawa EJA430A Pressure Transmitters.
- Measurement Range: The original EJA430A covered a pressure range from 0.1 to 100 kPa (differential pressure) or 0.1 to 10 MPa (gauge pressure), making it suitable for a wide range of applications.
- Accuracy: It boasted an accuracy of ±0.065% of the span, ensuring precise measurements in critical processes.
- Output Signal: The transmitter provided a 4-20 mA DC output signal, which was compatible with standard industrial control systems.
- Power Supply: It operated on a power supply of 10.5 to 42 V DC, offering flexibility in different installation environments.
- Process Connection: The original model featured standard process connections, such as flange or threaded connections, allowing for easy integration into existing systems.
- The original EJA430A used a dual-capacitance sensor design.The new model features a single-crystal silicon sensor, which offers superior performance in terms of sensitivity, stability, and resistance to environmental factors.
Features
- Dual-Capacitance Sensor: The original EJA430A utilized a dual-capacitance sensor design, which provided excellent stability and resistance to environmental factors such as temperature and vibration.
- HART Communication: It supported HART (Highway Addressable Remote Transducer) communication protocol, enabling remote configuration and monitoring of the transmitter.
- Robust Construction: The transmitter was housed in a durable enclosure that protected it from harsh industrial environments, ensuring long-term reliability.
- Oil and Gas: Measuring pressure in pipelines, wells, and refineries.
- Chemical Processing: Monitoring pressure in reactors, distillation columns, and other process equipment.
- Power Generation: Ensuring accurate pressure measurement in boilers, turbines, and cooling systems.
- Water and Wastewater: Monitoring pressure in water treatment plants and distribution systems.
Product Overview
- Measurement Range: The new EJA430A maintains a similar pressure range to the original model, from 0.1 to 100 kPa (differential pressure) or 0.1 to 10 MPa (gauge pressure), ensuring compatibility with existing applications.
- Accuracy: It offers an enhanced accuracy of ±0.04% of the span, providing even more precise measurements for critical processes.
- Output Signal: The new transmitter continues to provide a 4-20 mA DC output signal, but it also supports additional communication protocols such as FOUNDATION Fieldbus and PROFIBUS PA, offering greater flexibility in system integration.
- Power Supply: It operates on a power supply range of 9 to 42 V DC, providing improved energy efficiency and compatibility with a wider range of power sources.
- Process Connection: The new model retains the standard process connections of the original, ensuring easy replacement and integration into existing systems.
- Single-Crystal Silicon Sensor: The new EJA430A features a single-crystal silicon sensor, which offers superior performance compared to the dual-capacitance sensor used in the original model. The single-crystal silicon sensor provides higher sensitivity, better stability, and improved resistance to overpressure and corrosion.
- Enhanced Digital Signal Processing: The new transmitter incorporates advanced digital signal processing technology, which enables faster response times, improved noise rejection, and enhanced measurement stability.
- Advanced Communication Protocols: In addition to HART communication, the new EJA430A supports FOUNDATION Fieldbus and PROFIBUS PA protocols, allowing for seamless integration into modern digital control systems. These protocols enable advanced functionality such as remote configuration, diagnostics, and asset management.
- Intelligent Diagnostics: The new model is equipped with intelligent diagnostic capabilities, which continuously monitor the transmitter's performance and detect potential issues before they cause downtime. This helps to improve maintenance efficiency and reduce operational costs.
- Compact and Lightweight Design: The new EJA430A features a more compact and lightweight design compared to the original model, making it easier to install and handle in tight spaces.
